Hi
I have a 7 month new 50 gallon tank with 3 fishes and 4 corals ( LPS & softie ). I have 7 snails with different variety including 2 turbo snails. They all appear ok. About 1 month ago ( seems even longer , probably close to 2 months ), the tank started having algae issue. Mostly light brown algae, and there is a patch that's red algae with layers of film developing. The red film can become bigger that it flows as well. I have attached two videos and I couldn't get the red algae on the video.
I have tried a few things. 1) Cleanup using toothbrush 2) siphon the tank 3) doing weekly water change with 5 gallon ( 10% ) 4) reduce the LED light to 9 hours and most of the time without strong white LED, the power of the LED is reduced to 40% blue and 5% of the white. I have used GFO and active carbon. I recently switched to phosguard and purigen.
I won't say the issue has improved or worsen. I am looking for suggestions.
a) Should I change the LED to make it more proper ( this is an inexpensive LED like the one below )
b) Should I add an in-line UV light
c) I am in the process of adding a DIY algae scrubber
another question, the tank doesn't look this "pink". I turned on the white LED when i shoot the video, and I wonder what the base algae is. Meaning, the rock came in as dryrock, they were all "white". Now a lot of the rock are covered in dark brown kind of algae, but they also look quite pink in the video.
